Easy: in one way or another I regret selling them ALL. Mostly I regret selling the '86 ('85?) Cannondale I had back in those days. I don't know why, but methinks that it has something to do w/ how much riding that bike saw me through with NO complaints/hiccups/eyerolls. It saw me through all sorts of weather, all sorts of terrain, and transported me to all sorts of events. I rode that bike to my intern semester of teaching Jr. High! I *still* think those Cunningham brakes are cool...

Too many: an early 80's S&S Rainbow Cruiser, a mid 80's Diamondback Meanstreak ( my first MTB) a 1987 Schwinn Circuit, $795 Columbus SL; made in the USA with Suntour Sprint 6 speed indexed shifting. What really sucks is that I sold it in 1996 for 130 bucks to buy a……. 1996 VOODOO Wanga- which was a great frame until I sold and never collected all the money. A '97 Stumpjumper (actually gave the frame away??) Live and learn, I don't sell bikes anymore, just buy and keep!!

I am one that never regrets selling anything.
I just never get attached to materialistic things.

If I sell something, it is because I am no longer using it and have no purpose for it anymore. What I regret is the space it takes up if I keep it. What I enjoy is the fact that maybe somebody else is getting some use or enjoyment out of it.
